Tartarini™ Type FLR Pilot Operated Pressure Reducing Regulator

Type FLR pilot‑operated axial‑flow regulator delivers accurate, quiet high‑pressure control for transmission and distribution.

Type FLR is an accurate, pilot-operated, pressure reducing, axial flow regulator designed to meet a wide range of applications in high pressure transmission, city gate and large capacity distribution of suitably filtered natural gas.

Type FLR provides smooth and quiet operation, tight shut off and long service life. The regulator comprises of a main valve, a built-in actuator, a PRX, PSA or PS Series pressure reducing pilot and a Type SA/2 pilot supply pressure regulator when PRX pilot is used. The regulator 's superior performance is attributed to the combination of a number of features such as fully balanced plug, radial seal for lower sealing forces, double piston actuation mechanism, together with field proven pilots and two path control system.

Type FLR is designed to be used with fuel gases of 1st and 2nd family according to EN 437, and with other non-aggressive and non-fuel gases. For any other gases, other than natural gas, please contact your local sales office.

Características clave

  • Single-piece, integral flanged and ergonomic design of anti-rolling feature in the body
  • Higher capacity than same size top entry design and traditional split-body axial flow design
  • Fully balanced plug design for lower actuation forces, thus, able to achieve full stroke even with less than 0.5 bar / 7.25 psig pressure differential
  • Radial seal design resulting in low fluid velocity around the seating surfaces to reduce flow wearing
  • Compact and lesser weight design through double piston actuation mechanism compared to traditional diaphragm actuated mechanism
  • Ease of maintenance through modular design
